Four-row bearings provide maximum capacity in minimum space, combining the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings.

Their main application is on the roll necks of rolling mill equipment.  All four-row bearings are supplied as pre-set matched assemblies with all components identified to ensure correct installation sequence.

Tapered roller bearings (TRBs) utilize rolling elements that are shaped like a truncated cone (Figure 1), and are constructed so that all tapered surfaces converge at a common apex point on the bearing centerline to yield true rolling motion (Figure 2). Tapered roller bearings are generally used in lower speed, high load applications and are capable of absorbing radial and/or axial loads. The internal angles may be designed to tailor the bearing to the loading demands of a specific application. Tapered roller bearings are a separable two-piece design (cup and cone) (Figure 3); which, allows the end-use to optimize the internal clearance (and life) for each application when the bearing is mounted. PEER primarily manufactures single row (TS), sealed single row (LA), and matched set tapered roller bearings.

Specifications of 32917 bearings

32917 bearings  is made of chrome steel, is unsealed, and has a steel cage. This single row taper roller bearing is suitable for applications that support both radial and axial loads. This bearing's inner and outer races are made of chrome steel for durability and resistance to deformity under heavy loads. This bearing is open for lubrication in place. A steel cage evenly spaces rollers for reduced friction, vibration, and noise. This bearing supports heavier loads than bearings with comparable-sized ball bearings. This taper roller bearing is suitable for use as a wheel bearing.

Features of 32917 bearings

• High quality through hardened bearing steel
• Optimized, engineered internal geometry
• Highly consistent, reliable, and flexible manufacturing
• Globally interchangeable inch and metric designs
• Available integrated seal

Advantages of 32917 bearings

• Improved bearing reliability and life
• Integrated seal can improve contamination exclusion to, or replace, external seals in certain applications (consult your PEER Application Engineer)

Benefits of  32917 bearings 

• Extended bearing life equals longer equipment service life
• Longer intervals between scheduled machine maintenance results in lower ownership cost
